CROSS-REFERENCE TO RELATED APPLICATIONS

This application is a continuation of, claims the benefit of and priority to previously filed U.S. patent application Ser. No. 13/189,706 filed Jul. 25, 2011, entitled “TECHNIQUES TO DISPLAY AN INPUT DEVICE ON A MOBILE DEVICE”, which is incorporated herein by reference in its entirety.

BACKGROUND

Mobile devices are becoming increasingly smaller over time in order to facilitate transport, storage and convenience for a user. Along with the smaller form factors, however, mobile devices typically implement integrated displays with a limited amount of display area. This makes it difficult for a user to view content presented on the smaller integrated displays. To solve this problem, a user may couple a mobile device to an external display, such as a liquid crystal display (LCD) monitor, via a wired or wireless connection. The external display may have a larger amount of display area relative to the integrated display of the mobile device. In this configuration, content presented on the smaller integrated display of a mobile device may be replicated to the larger external display to enhance viewing by a user.

Despite the larger image presented by the larger external display, the smaller integrated display of the mobile device typically continues to present the same view as that shown on the larger external display. This seems redundant given that one purpose of the larger external display is to become a primary viewing device for the mobile device. In some cases, the smaller integrated display may be turned off to conserve power to the mobile device. In both cases, however, the smaller integrated display remains an underutilized resource of the mobile device. It is with respect to these and other limitations that the present improvements are needed.

DETAILED DESCRIPTION

Embodiments are generally directed to techniques for managing multiple display devices coupled to a mobile device. Some embodiments are particularly directed to techniques for presenting different content on each display device coupled to a mobile device. In one embodiment, for example, a mobile device may detect an external display device. The mobile device may be coupled to the external display device via wired or wireless connections. The mobile device may comprise an integrated touch sensitive display. Furthermore, the mobile device may implement a display manager arranged to present different content on each of the display devices, rather than identical content as presented by conventional solutions.

In an embodiment, for example, the mobile device may detect an external display device. In an embodiment, a display manager may present a digital input device on an integrated touch sensitive display of a mobile device, while simultaneously presenting multimedia content from an application on an external display coupled to the mobile device. In an embodiment, the digital input device presented on an integrated touch sensitive display of a mobile device may operate the mobile device. A digital input device may comprise, for example, a software version of a keyboard, a pointing device, a touch pad, or any other type of physical input device. In this arrangement, the integrated touch sensitive display may be used to replicate functions of a physical input device, without necessarily needing to connect any physical input devices to the mobile device. In this manner, an integrated touch sensitive display for a mobile device may be utilized as a custom input device for the mobile device, rather than simply presenting identical content as that presented on an external display device. As such, an integrated touch sensitive display is converted from a wasted resource to a productive resource of a mobile device.

In an embodiment, multimedia may be presented on the external display. In an embodiment, the multimedia may be presented in response to the operation of the mobile device through the digital input device.

In some cases, a physical input device may be coupled to a mobile device. In such cases, the integrated touch sensitive display may be used to augment functions of the physical input device. For instance, a physical pointing device such as a mouse may be coupled to a mobile device, and used to select content presented on an external display. However, the external display may not provide sufficient resolution or granularity to specifically pin-point content presented on the external display. In this case, the integrated touch sensitive display may provide a more detailed version of an area around a pointer positioned on the external display, thereby allowing a user to select a more precise location within the detailed version by tapping on the integrated touch sensitive display at the desired location. Other use scenarios exist as well.

Various embodiments may comprise one or more elements. An element may comprise any structure arranged to perform certain operations. Each element may be implemented as hardware, software, or any combination thereof, as desired for a given set of design parameters or performance constraints. Although an embodiment may be described with a limited number of elements in a certain topology by way of example, the embodiment may include more or less elements in alternate topologies as desired for a given implementation. It is worthy to note that any reference to “one embodiment” or “an embodiment” means that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one embodiment. The appearances of the phrase “in one embodiment” in various places in the specification are not necessarily all referring to the same embodiment.

FIGS. A-C illustrate block diagrams of possible embodiments of a mobile system 300. FIG. 3A illustrates a block diagram of an embodiment of a mobile system 300. In the illustrated embodiment shown in FIG. 3, the mobile system 300 may include a mobile device 310 and an external display 320 for the mobile device 310. The external display 320 may be coupled to the mobile device 310 via a connection 360. In an embodiment, the connection 360 may be over the shared media 160, as shown in FIG. 1. In an embodiment, the connection 360 may be a wireless connection. In an embodiment, the mobile device 310 may connect 360 to the external display 320 using a Wireless Display (WiDi) channel. Examples of an external display 320 may include, but are not limited to, a television screen and/or a computer monitor.

A mobile device 310 may include, but is not limited to, a laptop, a notebook, a handheld computer, a handheld enclosure, a portable electronic device, a mobile Internet device (MID), a tablet, a computing device with a touch screen, a slate and/or a personal digital assistant. The embodiments, however, are not limited to these examples. The mobile device 310 may include an integrated display 312. As discussed above, the integrated touch sensitive display 312 may be implemented as, but is not limited to, a touch screen, touch panel and/or touch screen panel.

When the mobile device 310 is coupled to the external display 320, the external display 320 may replicate the multimedia content currently displayed on the integrated touch sensitive display 312 of the mobile device 310. As discussed above, the multimedia content may include, but is not limited to, text, images, audio and video. Once the external display 320 and the mobile device 310 are coupled, the mobile device 310 may present a digital input device on the integrated touch sensitive display 312 while the external display 320 may continue to present the multimedia content.

In an embodiment, the combination of the external display 320 and the integrated touch sensitive display 312 of the mobile device 310 can mimic a desktop computer being docked with various input/output devices. For example, the external display 320 may function as the primary display while the integrated touch sensitive display 312 of the mobile device 310 may function as an input device.

An input device is a device which provides information to a processing device. Input devices may include, but are not limited to, a keyboard, a pointing device, a touch pad, a composite device, an imaging device and/or a video device. Further examples of input devices may include, but are not limited to, a mouse, a track pad, a digital camera, digital recorder, a webcam, a microphone, a scanner, a barcode reader, a pointing stick, a virtual pen, a joystick, a controller, a game controller, a remote, a computer keyboard, a trackball and/or any other type of physical input device. The embodiments, however, are not limited to these examples.

In an embodiment, the integrated touch sensitive display 312 of a mobile device 310 may display an input device. In an embodiment, the input device presented on the integrated touch sensitive display 312 may be referred to as a digital input device 370. The digital input device 370 may comprise hardware and/or software to replicate the functions of an external physical input device. In an embodiment, the digital input device 370 may mimic the functionality of the input device presented on the integrated touch sensitive display 312. A digital input device 370 presented on the integrated touch sensitive display 312 of the mobile device 310 may provide information to the external display 320. Using the digital input device 370 may reduce and/or eliminate the need to couple the mobile device 310 to external physical input devices.

For example, an integrated touch sensitive display 312 of the mobile device 310 may display a keyboard as a digital input device 370. A keyboard may be presented on the integrated touch sensitive display to operate the mobile device and the external display may present multimedia content in response to operation of the mobile device through the keyboard. When a user touches a letter on the keyboard presented on the integrated touch sensitive display 312 of the mobile device 310, the letter may appear on the external display 320 as if the user touched that letter on an external keyboard device.

For example, an integrated touch sensitive display 312 of the mobile device 310 may display a trackball as a digital input device 370. A trackball may be presented on the integrated touch sensitive display to operate the mobile device and the external display may present multimedia content in response to operation of the mobile device through the trackball. When a user touches the trackball presented on the integrated touch sensitive display 312, a pointer from the location of the trackball may appear on the external display 320.

For example, an integrated touch sensitive display 312 of the mobile device 310 may display a video remote with one or more of a stop, start, fast forward, rewind and/or play button. A video remote may be presented on the integrated touch sensitive display to operate the mobile device and the external display may present multimedia content in response to operation of the mobile device through the video remote. When a user touches a button on the video remote presented on the integrated touch sensitive display 312, the video remote may stop, start, fast forward, rewind and/or play on the external display 320 based on the user's touch.

The mobile device 310 may function as the input device presented on the integrated touch sensitive display. For example, the input device presented on the integrated touch sensitive display 312 of a mobile device 310 may be a keyboard. The keyboard presented on the integrated touch sensitive display of the mobile device may have the same functionality of an actual keyboard. For example, a user may touch the caps lock key and a letter key presented on the integrated touch sensitive display in order to capitalize a letter. Alternatively or in addition, a user may press multiple keys simultaneously to replicate a keyboard function, such as holding the shift key to capitalize a letter.

Alternatively and or in addition, the mobile device 310 may mimic the functionality of an external physical input device via one or more visual images, sounds and/or vibrations. The mobile device 310 may provide sensory output such as, but not limited to, output for a user's sense of sight, hearing and touch. The sensory output from the integrated touch sensitive display 312 of the mobile device 310 may assist the user in using the digital input device 370.

In an embodiment, the integrated touch sensitive display 312 of the mobile device 310 may mimic the functionality of an external physical input device via a visual depiction. For example, the integrated touch sensitive display 312 of the mobile device 310 may display a keyboard as a digital input device 370. The integrated touch sensitive display 312 may mimic the keyboard via the visual depiction of the various buttons of a full sized keyboard device. A user may touch a key on the integrated touch sensitive display 312 to mimic the pressing of one or more keys. In an embodiment, the integrated touch sensitive display 312 may mimic a keyboard by displaying a depressed key when the presented key is touched by a user. For example, a user may touch the letter “u” and the letter “u” key presented on the integrated touch sensitive display 312 may show a depressed “u” key. In an embodiment, the integrated touch sensitive display 312 of the mobile device 310 may display a mouse with a scroll wheel. The integrated touch sensitive display 312 of the mobile device 310 may show a visual image of where the mouse previously moved on the integrated touch sensitive display 312. Alternatively or in addition, the integrated touch sensitive display 312 may depict a moving scroll wheel when a user touches the displayed scroll wheel. The examples are not limited to the embodiments described.

In an embodiment, the mobile device 310 may mimic the functionality of an external physical input device via one or more sounds. For example, if the digital input device 370 presented is a keyboard, the mobile device 310 may provide a clicking sound when a user touches a key presented on the integrated touch sensitive display 312. If the digital input device 370 presented is a mouse, the mobile device 310 may provide a clicking sound when a user touches the left and/or right buttons depicted on the displayed mouse. Alternatively or in addition, the mobile device 310 may provide a noise when a user moves a mouse around the integrated touch sensitive display 312. If the digital input device 370 presented is a barcode reader, the mobile device 310 may provide a beeping sound when a barcode is read. The examples are not limited to the embodiments described.

Alternatively or in addition, the integrated touch sensitive display 312 of the mobile device 310 may provide a vibration or sensation to a user when a user touches a part of the presented digital input device 370. In an embodiment, the mobile device 310 may mimic the functionality of the input device via a touch or tactile sensation. In an embodiment, the mobile device may contain a motor and or other tactile technology in order to provide the sensation to a user. For example, if the digital input device 370 presented is a track pad, the mobile device 310 may provide the user with a sensation of the ball of a tack pad rolling across the integrated touch sensitive display 212. If the input device presented is a mouse, the mobile device 310 may provide a vibration when the left and/or right buttons presented on the integrated touch sensitive display 312 are touched by a user. Alternatively or in addition, the mobile device 310 may provide a different vibration when a scrolling wheel of the mouse is touched by a user. If the input device presented is a keyboard, the mobile device 310 may provide a vibration when a key on the integrated touch sensitive display 312 is touched. The examples are not limited to the embodiments described.

Using the integrated touch sensitive display 312 to replicate functions of an external physical input device may eliminate the need to connect one or more physical input devices to the mobile device 310. The integrated touch sensitive display 312 for a mobile device 310 may be utilized as a custom input device for the mobile device 310 and may be a productive resource of a mobile device 310.

FIG. 3B illustrates a block diagram of an embodiment of a mobile system 300. In an embodiment, a mobile system 300 may include multiple external displays 320A, 320B, 320C coupled to a mobile device 310. In an embodiment, the external display 320A, 320B, 320C may be coupled to the mobile device 310 via a wired or wireless connection. In an embodiment, one or more of the multiple external displays 320A, 320B, 320C may be coupled to the mobile device via a Wireless Display (WiDi) channel.

In an embodiment, one or more of external displays may present multimedia content. In an embodiment, one or more of the external displays 320A, 320B, 320C may present the same multimedia content simultaneously. For example, various external displays 320A, 320B, 320C may present the same multimedia content simultaneously so that users in a large ballroom may view the content, such as a presentation, from wherever they are seated. Alternatively or in addition, one or more external display 320A, 320B, 320C may present at least a portion of the multimedia content. For example, multiple displays may be used together to form one large display presenting the multimedia content. The examples are not limited to the embodiments described.

FIG. 3C illustrates a block diagram of an embodiment of a mobile system 300. In an embodiment, an external input 380 may be coupled to a mobile device 310. In an embodiment, the external input 380 may be a physical input device. In an embodiment, the external input 380 may be coupled to the mobile device via a wired or wireless connection. In an embodiment, the external input 380 may be wirelessly coupled to the mobile device using the connection that coupled the mobile device 310 to the external display 320.

In an embodiment, the integrated touch sensitive display 312 on the mobile device 310 may be used to augment and/or enhance functions of the external input 380. For example, an external input 380 may be a physical pointing device such as a virtual pen. The virtual pen 380 may be coupled to a mobile device 310 and may be used to select content presented on an external display 320. However, the external display 320 may not provide sufficient resolution and/or granularity to specifically pin-point content presented on the external display 320. The digital input device 370 on the integrated touch sensitive display 312 of the mobile device 310 may provide a more detailed version of an area around a pointer positioned on the external display 370. This may allow a user to select a more precise location within the detailed version by tapping on the input device 370 on the integrated touch sensitive display 312 at the desired location.

In an embodiment, the integrated touch sensitive display 312 on the mobile device 310 may be used as a supplemental device along with the external input 380. For example, a computer workstation often has multiple external devices such as a keyboard and a mouse. In an embodiment, the mobile system 300 may have a physical keyboard as an external input 280 and the input device 370 on the integrated touch sensitive display 312 of the mobile device 310 may be a mouse. By having the mobile device 310 act as an input device, a computer workstation may be easily simulated without the need for multiple external devices. The examples are not limited to the embodiments described.

FIG. 4 illustrates exemplary digital input devices 425A, 425B, 425C presented on an integrated touch sensitive display 410 of a mobile device. As shown in FIG. 4, the integrated touch sensitive display 410 on the mobile device 405 may alternate between various digital input devices 425A, 425B, 425C and the multimedia content 415 while coupled to an external display of the mobile device 405.

In an embodiment, the mobile device 405 may present a keyboard 425A as the digital input device 425 on the integrated touch sensitive display 410. In an embodiment, the integrated touch sensitive display 410 of the mobile device 405 may automatically present a keyboard 425A as the digital input device 425 when the mobile device 405 is coupled to an external display.

In an embodiment, the integrated touch sensitive display 410 of the mobile device 405 may wait to receive information about the digital input device 425.
